A house painter mixed 5 gal of blue paint with every
9 gal of yellow paint in order to make a green paint.
Which ratio of gallons of blue paint to gallons of
yellow paint will make the same shade of green
paint?

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

your answer would be 12

6

step-by-step explanation:

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
